STORM WINDOW FASTENER Filed `May l2, 1938 @Dew/07" Patented Nov. 12, 1940 l UNITED STATES PATENT `OFFICE 4 3 Claims.

This invention relates to improvements in storm window fastenings.

One of the objects of my invention is the provision of a storm window fastening for use in connection with a storm sash which is hingedly secured to the frame of the usual window in a home or other building structure in which the storm sash can be quickly and positively locked in closed position and equally as quickly and easily unlocked and opened from the inside of the storm sash.

Another object of the invention is the provision of means in the fastening vdevice for permitting opening of the storm sash to various desired degrees and for retaining the sash in the desired position.

A further object of the invention is the provision of quick detachable means for connecting and disconnecting the window fastener relative to the main window frame.

Still another object of the invention is the provision of means for quickly and easily detaching the fastening device from the storm sash itself to permit more compact storage of the sash.

These and other objects and advantages of the invention will more fully appear from the following description made in connection with the accompanying drawing wherein like reference .characters refer to the same or similar parts throughout the views, and, in which:

Fig. 1 isa fragmentary vertical section through a window frame showing a storm sash and my improved fastening device in side elevation;

'r Fig. 2 is-an enlarged side view of the fastening device with portions of the frame and sash;

Fig. 3 is a View similar to Fig. 2 taken at rightangles thereto;

Figfl is a sectiontaken approximately on the line 4-4 of Fig. 3;

Fig. 5 is a section taken approximately on the line 5-5 of Fig. 3 and Figs.` 6, "l, and 8 are detailed perspectives of several of the detachable connections used with my invention.

In*4 the drawing there is shown a portion of window frame 9 to which is hingedly secured at its upper edge a storm sash I0. The sash is adapted to swing outwardly to the position shown in Fig. 1 or inwardly to a closed position within the window frame 9. A jamb II in the window frame provides an abutting surface for the storm sash when closed.`

The window frame and storm sash are additionally connected by a jointed lever comprising arms I2 and I3. These arms are pivotally connected by means of a friction joint. 'I'he arm I2, as shown in Fig. 5, has an aperture I4 therein which is defined by a small flange, and a frustaconical sleeve I5 is secured within the aperture I4 in any suitable manner such as by punched 5 portions I6. The sleeve I5 is adapted to fit within a slightly'larger sleeve I'I which is secured in the lever arm I3 in the same manner described for the othersleeve and arm, and a bushing or friction element I8 is interposed between the two sleeve elements. The sleeve II isi covered at its outer end by a cap I9, and said cap has a bolt 20 extending therethrough and into the smaller sleeve I5 where it passes through a flanged disk 2|, the' latter being wedged into said smaller sleeve I5. A compression spring 22 is mounted on the bolt 20 between a pair of locked nuts 23 and the flanged disk 2l. By moving the nuts 23 on the bolt 2D the frictional drag between the two conical sleeves may be varied. The frictional joint permits outward swinging of the storm sash to any desired degree, and the sash will be held in its desired position until force is applied thereto to change the position of the` sash.

'I'he lever arm I2 is provided with a flange 24 along one edge thereof and the lever arm I3 is provided with a flange 25 along its opposite edge. The flanges extend at both ends of each lever arm at a height which is uniform throughout the longitudinal edge of each of the lever arms. Each of said flanges is continued atleast partially around the ends of the lever arms but at a reduced height so that the end portions of said flanges cannot contact each other when the arms of the lever are rotated around their friction joint connection. The reduced flanged portions are principally for reinforcement of the lever arms. The flanges extending along the longitudinal edges of the lever arms are, as shown in Fig. 3, of such height that they will contact each other when the lever arms are brought into substantially parallel relationship. When the storm sash is closed the arms of the lever are collapsed by forcing their friction jointv connection downwardly and inwardly with movement of the arms and the sash until said lever arms reach the downward dotted line position indicated in Fig. 1. At this point said lever arms are substantially parallel. 'I'he friction joint is then collapsed using the outer or larger frusto-conical sleeve I1 as a handle and the arms are swung inwardly and upwardly to the upward dotted position shown in Fig. 1. In this latter position which is the same as that illustratedin Figs. 2 and 3 the storm sash is locked against opening from the outside due to the fact that the lever arm flange 25 over-lies the iiange 24 and any attempt to pull the storm sash open from the outside will be prevented. In order to unlock the storm sash for opening from the inside it is necessary only to swing the lever arms to their downward position and push the sash open.

The lever arm I2 is, of course, adapted to be pivotally secured to the window frame and such connection is made with the window jamb II. The jamb II carries an apertured plate 26 which is secured at its ends byscrews 21 to the jamb in the window frame. The medial portion of the securing plate 26 is bent outwardly, as best shown in Fig. 3, and this medial portion is provided with an aperture 28, as indicated in Fig. 4. The outwardly slanting portions of the plate 26 are provided with apertures 29 to slidably receive a latch element 30. This latch element, as shown in Fig. 8, is provided with reduced extensions 3| which are adapted to slide in the apertures 29 in the plate 26, shoulders 32 limiting the movement of the latch 30 relative to the latch plate 26. The latch 30 is provided with a slot 33 which at its lower end is enlarged as at 34. The enlarged portion 34 of said slot is preferably approximately the same size as the aperture 28 in the stationary plate 26. The lever arm I2 at its inner end has a metallic button journalled therein so that said journal is freely rotatable relative to said lever arm I2. 'Ihe button 35 is provided with an annular groove 36, the head of the button being slightly smaller than the enlarged portion 34 of the slot 33 in the slidable latch 30, and the annular groove in the button 35 being of such size that the reduced portion of the button provided by said groove will fit the smaller and upper end of said slot 33.

The slidabler latch 30 is so arranged relative to the opening 28 in the stationary plate 26 that said latch will fall to its lowermost position under gravity and present the upper narrow portion of the slot 33 in registration with said opening 23. To insert the pivot button 35 in the anchoring plate, the latch 33 must be elevated by pushing upwardly on its lower extension 3I to align the enlarged portion 34 of the slot 33 with said stationary plate opening 28. The button 35 may then be inserted through the openings 28 and 34, and when the slidable latch 36 is released it will fall and thereby engage the side edges of the narrow slot 33 between the walls Iof the groove 36 in the button 35. The lever arm I2 is thus connected to the window frame jamb strip for pivotal movement without displacement under normal usage. My reason for journalling thel button 35in the lever arm I2 is to prevent pivotal movement from being transmitted from the lever arm I2 to the button and thereby possibly through frictional engagement cause'an accidental elevationl of the `slidable latch 30.

The outer end of the lever arm I3 is detachably and pivotally secured to the storm sash I6. An angle plate 31 is secured by screws 38 which extend through openings 39 in the angle plate and into the storm sash I 0. The other facey of the angle plate 31 from the vsecuring face is'provided with an opening 4I] which is adapted to receive a metallic button 4I journalled in the lever arm I3 and provided with an annular groove 42 in the same general manner as the button 35 in the lever arm I2. A right-angle latching device 43 is adapted to t within the angle formed by the bracket 31, one face of said latch having an elongated slot 44 through which the upper most of the bracketretaining screws 38 extends to secure said latch in slidable relation tc said bracket plate, The other portion of the latch 43 has a slot 45 which extends inwardly from the lower edge of the latch 43. The open ended slot 45 is adapted tcl fit down over the button 4I with the edges of said slot tting in the annular groove in 42 in said button 4I. The button can be released by pushing the latch upwardly out of engagement with said button 4I. When the lever arm I3 is connected to the'bracket 31 by means of the latch 43, said latch can be rmly secured in locking position by merely tightening the upper most screw 38 so that said latch is in firm frictional engagement with the bracket 31.

With the two above noted detachable connections between the lever arms and the window frame and the storm sash it is possible to quickly disconnect the storm sash and lever arms as a unit from the window frame, and when the storm sash is taken down and stored for the summer the lever arms can be entirely removed from the sash by disconnecting them with the latch mechanism shown in Figs. 6 and '7. Thus the sashes can be neatly piled without interference of the lever arms.

From the foregoing it will be seen that I have provided a storm sash fastener which is of neat appearance and which can be readily manipulated to either set the sash at any desired opened or partially opened position or which can beV quickly and easily locked from the inside to prevent opening thereof from the outside. The flanges 24 and 25 on the two lever arms provide a strong and simple locking device when the lever arms are swung to their upward positions shown in Figs. 2 and 3, and the reduced end portions of said flanges provide eiective reinforce'- ment for the lever arms. In addition the lever arms can be disconnected at either end from either the window frame or the storm sash, as

described above.

It will, of course, be understood that various changes may be made in the form, details, arrangement and proportions of the various partsy without departing from the scope of my invention.

What is claimed is:

1. In a storm sash fastener for a sash hingedly` yextendiniT at least partially around the ends of said arms to provide non-contacting reinforcing flanges at the ends of said arms.

2. In a storm sash fastener for a sash hingedly connected to a window frame. a lever comprising a pair of arms, an enclosed adjustably tensioned friction joint connecting said arms, the opposite ends of said arms having projecting elements rotatably mounted thereon, brackets on said window frame and said sash having openingsto receive said projecting elements, and gravity actuated catches slidably mounted on said brackets and adapted to engage said projecting elements to secure them in the openings in said brackets.

3. In a storm sash fastener for a sash hingedly connected to a window frame, a lever pivotally connected between said sash and said frame, said eve-r having a joint intermediate its ends comprising a pair of frusto-conical elements, one element being smaller than and fitting into the other of said elements, a friction device interposed between said elements, a cap on the end of said larger element, a bolt extending through said cap and into the interior of said smaller element, a plate in said smaller element, said bolt passing therethrough, and a lspring retained on said bolt under compression between the inner end of said bolt and said plate, the tension of said spring being adjustable to vary the frictional resistance of -said friction device and maintain said sash in position when set at an angle to said window frame.
